Enter the following command to see the property of any logical drive subordinate
to the target RAID Controller.

Value "C" shows the number of the RAID Controller. Value "L" indicates the
number of a logical drive.
In the example below, both the RAID Controller and logical drive numbers are
assumed to be 1.
# raidcmd property –tg=ld –c=1 –l=1 <ENTER>

Battery refresh may take place if a new battery is installed. The system operates in
the write through mode before the charge-discharge cycle is completed. Check the
battery status again after about 12 hours.
The auto switch means that, in general, the write back is automatically switched
to the write through or vice versa depending on the battery status. We normally
recommend this setting.
For details of write cache setting, refer to the User's Guide attached to the RAID
Controller or the "Universal RAID Utility User's Guide" stored in
EXPRESSBUILDER attached to the Express5800 series server.
If a battery is connected after creation of logical drives, "Cache Mode (Setting)"
may be set to "Write Through". Set the value to "Auto Switch" if necessary.
